One of the coolest scenes in all of the Star Wars films is when Boba Fett meets his demise in the gullet of the Sarlacc. The Sarlacc is the giant maw of death with all the teeth and tongue tentacles that Jaba the Hutt tries to feed Luke and others to out in the desert.
If you are a fan of that particular scene, you should check out these Sarlacc toiler decals. They are rather gross in a way, but really cool at the same time. The sticker idea came about as the result of poop jokes according to the maker.
Someone said, "Toss Boba Fett in the Sarlacc" and the rest is history. The result is some sort of stickers that you stick to the inside of your toilet. I will assume them to be waterproof and turd proof considering where they are supposed to stick.
I also imagine that if you want your own set, you had better get them quick. I see no indications that these are licensed and Disney/Lucasfilm is vigorous in killing any non-licensed use of Star Wars content. The decals will set you back $25. If they will make a teen-age boy hit the toilet with greater frequency, it's $25 well spent.
